Doc on 1. http://maven.apache.org/plugins/maven-deploy-plugin/usage.html as well as 2. http://maven.apache.org/plugins/maven-deploy-plugin/deploy-file-mojo.html as well as 3. http://maven.apache.org/plugins/maven-deploy-plugin/file-deployment.html (link "Disable timestamps suffix in an artifact", currently broken!) currently mentions a uniqueVersion.
This appears to be broken at least with Maven v3.3.9. For example, if I do:
Note hello-impl-0.1.0-20160618.170929-1.jar despite -DuniqueVersion=false.
If this possibility has been removed, as I have the feeling it has been from posts incl.
MDEPLOY-44 (that was about adding uniqueVersion to deploy just like, supposedly, it is on deploy-file; this is about it not even working on deploy-file, anymore), then before you close this as WONTFIX, I would argue this current half removal is confusing to say the least ..
If this is not coming back, then the uniqueVersion configuration should be fully removed from maven-deploy-plugin, and the documentation in at least 3 places referred to above should be cleaned up accordingly.
